Specification forming part of Letters Patent No. 45,363, dated December 6, 1864; antedated November 30, 1864.

ducing such strips from rolled metal drawnto a uniform thickness and of the proper width, and then soldering the rows of type-heads to Y the strips in the manner hereinafter described.

I out from a sheet of rolled zinc or other metal strips in width equal to the required height of the body of the printing-type. These strips I draw through a drawing-tool suitable for the purpose and similar to the tool' employed in drawing wire, thus securing for them the requisite uniformity of thickness. To one .of the edges of each of such strips I a row of the electrotyped I then expose the strips strips and heads.

fastened together to. heat and type-heads so sufficient to melt the solder on the backs-of the type-heads, by this means permanently fastening the row of type-heads to the strip.

Another mode of securing the type-heads to the strip is to have a bar of cast-iron contain ingone or more grooves, each groove about three-eighths of an inch in depth, and in width equal'to the of the grooves I place a row of type-heads, faces down, and on top of the row of type-heads I place the strip edgewise. I then expose the bar to heat sufficient to melt the solder on the backs of the rows of typeheads.- The strips, being allowed to cool, are

withdrawn from the grooves and afterward cut up into single type by means of the cuttin g-machine that, I have described in another application for Letters Patent.

Havingthus described my invention, what I claim, and desire to secure by Lett-ers Patent,

The manufacturing of printing-type by form-- ing the bodies thereof out of a strip of rolled metal drawn to a uniform thickness and of the proper width, and soldering to one edge of the strip a row of electrotyped type-heads, and

then cutting the said strip into single type, in the manner substantially as above described.
